Golf is back at the Olympics after a 112-year hiatus, complete with capybaras

Golf is back at the Olympics for the first time in 112 years. A total of 120 golfers will take to the greens at Campo Olimpico de Golfe, including Canadians David Hearn, Alena Sharp, Graham DeLaet and Brooke Henderson.

The brand new course was built in an old sand quarry and designed by American architect Gil Hanse. The par-71 course plays 7,128 yards for the men's competition and 6,245 for the women's. Hanse has designed courses around the U.S., in Scotland and one that will open in Dubai next year.

Though work on the Rio course started in November 2012, there have been delays, debates and controversy about its location and construction. Some questioned the impact the course would have on the environment — it was partially carved out of a nature reserve.

But animals don't seem to mind it. Owls, monkeys and a crocodile have been spotted on the course, as well as a small group of capybaras.

At least 40 of the giant rodents that used to inhabit the course have been moved into the marsh behind the fences. An official says at least one has evaded capture and remains somewhere on the golf course. Here a capybara was spotted by a water hazard.

Though practice rounds are being played, organizers are still putting finishing touches on the clubhouse, pathways and the parking lots.

As for the course itself, there are virtually no trees but there is lots of sand. Most of the fairways are lined with sand waste areas, and the course has 79 bunkers.

The fairways are wide, the greens not too big and the sand traps are in play around each and every one. Hanse said he expects the most drama to unfold on the course's final three holes.

The first round of men's golf starts Thursday, while the women start a week from then, on Thursday, Aug. 17.
